Though the P1022 DIU is not VGA-compatible device, to meet the 'vga' name used in u-boot, the vga alias node is added for P1022 in this patch. At the same time, a display alias is also added so that no other components grow dependencies on the vga alias node. Signed-off-by: Jason Jin --- V2: Update the description and also add a display alias. V3: Add code comment for the inaccurate vag name. Thanks for Scott's input. arch/powerpc/boot/dts/fsl/p1022si-post.dtsi | 2 +- arch/powerpc/boot/dts/fsl/p1022si-pre.dtsi | 3 +++ 2 files changed, 4 insertions(+), 1 deletion(-) diff --git a/arch/powerpc/boot/dts/fsl/p1022si-post.dtsi b/arch/powerpc/boot/dts/fsl/p1022si-post.dtsi index e179803..be49300 100644 --- a/arch/powerpc/boot/dts/fsl/p1022si-post.dtsi +++ b/arch/powerpc/boot/dts/fsl/p1022si-post.dtsi @@ -174,7 +174,7 @@ /include/ "pq3-gpio-0.dtsi" - display@10000 { + display: display@10000 { compatible = "fsl,diu", "fsl,p1022-diu"; reg = <0x10000 1000>; interrupts = <64 2 0 0>; diff --git a/arch/powerpc/boot/dts/fsl/p1022si-pre.dtsi b/arch/powerpc/boot/dts/fsl/p1022si-pre.dtsi index 1956dea..362ac51 100644 --- a/arch/powerpc/boot/dts/fsl/p1022si-pre.dtsi +++ b/arch/powerpc/boot/dts/fsl/p1022si-pre.dtsi @@ -50,6 +50,9 @@ pci0 = &pci0; pci1 = &pci1; pci2 = &pci2; + /*inaccurate vga name for U-Boot compatibility*/ + vga = &display; + display = &display; }; cpus { -- 1.8.0
